Activity Streams is an open format specification for activity stream protocols , which are used to syndicate activities taken in social web applications and services, similar to those in Facebook 's, Instagram 's, and Twitter 's. ^[1]

The standard provides a general way to represent activities. For instance, the sentence "Jack added Hawaii to his list of places to visit" would be represented in ActivityStreams as actor:jack, verb:add, object:Hawaii, target:placestovisit.

Implementors of the Activity Streams draft include Gnip , Stream, Stream Framework, and Pump.io .

The largest open source library (based on watchers) is Stream Framework, the authors of Stream Framework also run getstream.io. In addition there is a trend of SOA (service-oriented architecture) where third parties power this type of functionality. ^{[ citation needed ]}
